Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lamp tube production, and particularly relates to a lamp tube pressing mould. Background Art
[0002] A lamp tube is a device for emitting light, usually composed of a metal filament or semiconductor material. The lamp tube plays the role of emitting light, displaying and transmitting signals in the circuit. An aluminum substrate is an electronic component, mainly used to carry and fix electronic components, such as LED lamp beads. The relationship between the aluminum substrate and the lamp tube is that it provides a stable working platform for the lamp tube and helps the heat dissipation of the lamp tube.
[0003] The aluminum substrate of the lamp tube needs to be made using a mold. The aluminum raw material is placed in the mold, and the aluminum material is filled into various parts of the mold under high pressure and high temperature conditions. This process will make the aluminum material arranged tightly to form an aluminum substrate with good thermal conductivity and stability. After the die-casting is completed, the aluminum substrate is taken out of the mold and allowed to cool naturally to room temperature.
[0004] However, when the mold is extruding the aluminum substrate, an electric push rod that can move up and down is used to roll and extrude the edge of the aluminum substrate. In this process, it is easy to cause the two ends of the aluminum substrate to fall off from the inside of the mold. At the same time, after extrusion molding, the overall temperature of the aluminum substrate is high. After cooling, it is easy for the edge to stick to the mold. When the aluminum substrate is taken out of the mold manually, it is easy to deform due to adhesion and pressure. Utility Model Content

[0023] During the specific implementation: the two ends of the lamp tube aluminum substrate 3 are inserted into the placement groove 6 on the inner side of the pressing mold body 1. The interior of the lamp tube aluminum substrate 3 is hollow. The two ends of the lamp tube aluminum substrate 3 are sleeved on the outside of the limiting column 7 below the placement groove 6. The electric push rod 4 is used to extrude the edge of the lamp tube aluminum substrate 3. The limiting column 7 can prevent the lamp tube aluminum substrate 3 from warping when the electric push rod 4 is extruded.
